30 amp fuse Blown (E55 Break Down)

[markevo]

My ongoing nightmere continues ....Found that the 30amp fuse in rear fuse block next to large battery in boot has blown . Replaced and car started .......drove for ten mins and fuse blown again .....replaced and then checked it to find that fuse was hot !!! Any thoughts ???

What does your handbook say the fuse is for?

Not listed in handbook but it has to do with the fuel pumps as they stoped working

I have a wiring diagram which I used when installing my sub.

This only shows fuses in the passenger compartment, and under the carpet on the left hand side of the boot.

If you are talking about these second set of fuses, only fuses 1 and 2 which are near the bottom are 30amp. Fuse one is the one nearest the bottom as you look at it - where fuses go up the left hand side and relays are on the right.

Fuse 1 is the driver seat power. Fuse 2 is passenger seat power.

Fuse 4 is apparently 20amp, and is the fuel pump fuse.

Could it be the fuel pumps are dodgy and drawing too much current?

@ JohnEBoy ....They are under boot carpet where large battery is . Fuse holder is on o/s of the battery . The fuse in question is the large type of fuse H/D 30amp .
I agree with you it may be something to do with the pumps as when this fuse blows it knocks out the pumps !!

Hmm, the only other thing I can think of is a short - maybe at the pump end.

If you check out my other thread I was thinking it was pumps in the beginning and looked at most things then found that it was only a bloody fuse lol ......now I just need to find out what feeds it

Found out its a faulty pump drawing to much current .so all I need is to id which one now

:bannana:

Do I win a prize?

 

[markevo]

hahahahah erm do you know what part number for the drivers side is ?? I have two to choose from
MA211 470 17 94 ( i not sure but think this is passenger side)
OR
MA211 470 50 94 ( could this be the drivers side)

I only need the pumps not sender

Haven't got a clue for part numbers - I'd be contacting my inde for those in the morning.
